Because it actively promoted "it works on my machine" and "snowflake" installs. Supporting a legacy docker app (ie something that was shipped two years ago) is a massive nightmare, because the build system used to make it is almost certainly not going to work. This means keeping the software patched becomes a massive massive pain. (mind you the same argument can be said for statically compiled binaries) The assumptions, the wrapper, and the plain horror that is the storage system is just such an arse.
